2 Claims.

This invention relates to a recoil controlling device for guns adaptedto fire projectiles. The device comprises a body which may be suitablyattached to the muzzle end of a gun barrel, said 5 body having acylindrical gas chamber therein and having an inlet portion and a sealport at the rear and forward ends of said chamber, respectively, and ashoulder extending laterally from the inner end of the seal port to thesidewall of the chamber, said device having a plurality of dischargeports extending rearwardly and outwardly from the forward part of thechamber, adjacent the shoulder therein, whereby the gasses issuing fromsaid discharge ports and reacting against said shoulder minimize recoilwhen the gun is fired. A series of bafile ports extend through the sidewall of the chamber between the inlet end of the chamber and therearward ends of the discharge ports, and these bafiie ports areinclined forwardly and outwardly and intercept the products ofcombustion issuing from the discharge ports thereby minimizing blastagainst the operator of the gun.

In the accompanying drawing,

Fig. 1 is a central longitudinal section through the muzzle end of a gunbarrel and through the recoil controlling device mounted thereon, and

Fig. 2 is a transverse section through said device on the line 2-2 ofFig. 1.

Referring to the drawing, l indicates the muzzle end of a gun barrel thebore of which is indicated at 2, and A indicates the recoil device,mounted on the barrel. The body 6 of the recoil device is formed with acylindrical gas chamber 1 and with a collar 5 at one end which forms aninlet to the chamber and a means for attaching the device to a gunbarrel. The barrel is shown with external threads 3, and the collar hasinternal threads which engage the threads on the 40 barrel. A seal port8 extends from the forward end of the gas chamber through a cylindricalport 9 at the forward end of the body, the seal port being in axialalinement with the collar and also with the bore of the barrel. Anannular shoulder 6 extends from the inner end of the seal port to theside wall of the chamber, and a plurality of discharge ports ID, in anarcuate series, extend rearwardly and outwardly from the forward part ofthe chamber adjacent said shoulder. A plurality of bailie ports H, in asimilar series, extend through the side wall of the chamber at the rearof the discharge ports, the baffle ports inclining forwardly andoutwardly.

When the gun is fired recoil is minimized by the discharge of theproducts of combustion through the discharge ports l0 and the reactionagainst the shoulder 6 The discharge from these ports is intercepted bythe discharge from the forwardly inclined baflie ports and therebyblastagainst the operator of the gun is minimized.

What I claim is:

i 1. A recoil controlling device for guns adapted to fire projectiles,comprising a body adapted for attachment to the muzzle of a gun barrel,said body having a cylindrical gas chamber therein and having an inletport and a seal port at the rear and forward ends of said chamber,respectively, and a shoulder extending laterally from the inner end ofthe seal port to the side wall of the chamber, said device having aplurality of discharge ports extending rearwardly and outwardly from theforward part of the chamber, adjacent the shoulder therein, and a seriesof baffle ports extending through the side wall of the chamber betweenthe inlet end of the chamber and the rearward ends of said dischargeports, said bafile ports being inclined forwardly and outwardly.

2. A recoil controlling device for guns adapted to fire projectiles,comprising a body adapted for attachment to the muzzle of a gun barrel,said body having a cylindrical gas chamber therein and having an inletport and a seal port at the rear and forward ends of said chamber,respectively, and a shoulder extending laterally from the inner end ofthe seal port to the side wall of the chamber, said device having anarcuate series of discharge ports extending rearwardly and outwardlyfrom the forward part of the chamber, adjacent the shoulder therein, andan arcuate series of baflle ports extending through the side wall of thechamber between the inlet end of the chamber and the rearward ends ofsaid discharge ports, each series of ports extending around the side andtop portions of the body, only.
